Entry Lighting
The headlamps, taillamps, license
plate lamps, back-up lamps, dome
lamps, and most of the interior lights
turn on briefly when the Remote
Keyless Entry (RKE) 
button is
pressed, or when the door handle is
pulled on a keyless access vehicle.
See Ignition Positions (Key Access) or Ignition Positions (Keyless Access).
After about 30 seconds the exterior
lamps turn off, then the dome lamps
and remaining interior lights dim to
off. Entry lighting can be disabled
manually by changing the ignition
out of the OFF position, or by
pressing the RKE 
button.
This feature can be changed. See Vehicle Personalization.
